I Walid Saqqa, a geologist since 1974, Mid of June, the date at which I got my Bachelor degree from Mosul/Iraq. I have been worked as a demonstrator after graduation at the Faculty of Science, Baghdad University for two years and a half. After that, I have been worked for some years (1980-1983) in the mining sector of Jordan, during which time I joined the master program of Geology at the University of Jordan to achieve a Master degree in Geology in 1983. After that I have been worked for one year (1983-1984) as a teaching assistant at the Yarmouk University, where I granted a scholarship in the collaboration with the 'DAAD' organizaton to get a 'PhD' degree in Geology from Germany, which I have been completed in 1989. Currently I hold a professor rank, and I'am working since then (1989) as an academic in reseach and teaching selective core & elective courses including sedimentolgy & sedimentary rocks, sedimentary basin analysis, paleoenvironments, stratigraphy and physical geology. Besides another courses I taught such as the geomorphology, petroleum geology, environmental geology, field geology & economic geology.

Mona Loa Volcano.
Located in the Hawaii islands, this is one of the five volcanoes that make up the Island of Hawaii in United States. This is the largest volcano in the world in terms of volume. It holds 18,000 cubic miles of magma and it is at a height of 13680 ft above sea level (which is usually lower compared to its peers). It was erupting for more than 700,000 years. The last volcanic eruption occurred in March 1984 and it lasted for more than 24 days causing heavy damage to the people and surrounding areas. Though they were not much explosive, the viscosity of their magma fluid will be very low. As the result, the movement of hot magma would be much faster compared to other volcanoes causing great destruction to the neighborhood areas.
Mount Etna, Italy.
Perched above the lighted city of Catania, Mount Etna hurls a fountain of fire skyward as rivers of lava spill down its flanks. In spite of its dazzling displays, Mount Etna is a relatively safe volcano with rare, compact eruptions and slow-flowing lava that gives people a chance to escape.
